Histomorphometry of Golden Hamster Ovaries

Introduction: genital system is important herd in animal's creation. it is necessary for animalreproduction. mammal has two sex in genital system such as male and female in separatedanimals. animal reproduction destroyed by disorder of genital system. in this case, animalscannot produce an animal similar to them. finally it cause overthrow a species of animals.methods: histomorphologic characteristic of hamster ovary studied in this research fora human model. 5 right and 5 left ovary of puberty hamster is studied. studied biometricparameters were length, wildness and thickness.results: this research results showed which right hamster ovary had 5/08±1/6mm in length,3/05 ± 0/56 mm in wide ,and 2/88 ± 0/327 mm in diameter and left ovary had 4/68 ±1/253 mm in length, 2/2 ± 0/703 mm in wide and 2/4 ± 0/609 mm in diameter. counteringof different type of hamster ovarian follicles were showed which number of primordialfollicles were 1628/33± 305/6049, number of primary follicles were 307/33 ± 56/76, numberof secondary follicles were 140 ± 60/63, number of tertiary follicles were 9± 0 and number ofgraafian follicles were 8 ± 3/6. total count of hamster ovarian follicles was 2192/66± 178/46.histological studies showed which covering epithelium, parenchyma of hamster ovary issimilar to another mammal, and zuna plucida is forming in primary follicles when two cuboidalcell layers are observed around oocytes.conclusion: finally, because hamsters has short living period in comparing to human,therefore they have low ovarian follicles and oocytes but hamster ovarian follicles and oocytewere similar to human follicles and oocyte in histologic characteristics.
